Hey guys & Gals:The original fresh air intake was a hole on the RH side of the nose bowl, and connected to the fresh air valve on the fire wall. (also on the RH side of the fire wall) Aluminum tubing connected the two (now we use SCAT) and there was an additional control on the panel. Talk to your mechanic, but I would think that anything that could/would change the cooling of the engine is a MAJOR alteration and requires FAA approval.

I'm not so sure that that wasn't standard equipment on some 415C's. Mine has the vent air and no record of it ever being added. Doesn't look like an add on to me; but after 50 years I might not be able to tell.

Just cut a hole in the cowl and get a control box from Aircraft Spruce or such. Run a SCAT hose from the cowl to the box on the firewall - you got really cool air, all you would need, and are not starving the engine for any cooling air. I am in the process of adding such a vent on mine now.
